There’s a dataframe X with “Year”, “Month” and “Day” as integer below,

  Year Month Day A B C ...
0 2020    10  10
1 2021     1   1 ...
2 2022     1  10 ...
3 2023    10   1 ...
...

There’s another dataframe Y with “Date” as string to be transformed from X, while other columns keep intact. The format is expected to be “YYYY-MM-DD”.

  Date       A B C ...
0 2020-10-10
1 2021-01-01 ...
2 2022-01-10 ...
3 2023-10-01 ...
...

What’s the Pandasonic way to make it through, ideally in 1liner ?
